DlPPlNG-FRAME.

SPECIFICATION forming part of Letters Patent No. 241,499, dated May 17,1se1.

Application filed August 17, 1880. (No model.) Patented in FranceSeptember 20, 1879.

To all whom it may concern:

Be it known that I, ANDRE: LYoN, of Algiers, Algeria, have invented anImproved Tenter or Dipping Frame for Use in Dyeing, (for which I havereceived French patent for fifteen years, dated September 20, 1879, No.132,790,) and I do hereby declare that the following is a full, clear,and exact description of the same, reference being bad to the annexedsheet of d rawings, making a part of the same.

My invention relates to an arrangement of adjustable tenter or dippingframe for use in redyeing silk fabrics, whereby perfect evenness ofcolor is obtained.

In the accompanying drawings, Figure 1 shows a plan of the improvedadjustable dipping-frame, and Fig. 2 an end view of same. Fig. 3 showsthe frame in position upon the dye-vat, while Fig. 4 shows differentviews of the means of attaching the fabric to the frame.

The same letters of reference indicate like parts in all the figures.

In the ordinary mode of dyeing silk fabrics the fabric, being fixed onpins or hooks, is stretched unequally at different parts, besides which,owing to the shrinking of the fabric after its immersion in the vat, thefibers are subjected to excessive tension, which prevents the dye frompenetrating uniformly.

The above objections, as well as others, such as the oxidation of thehooks and spotting and oth er blemish es on thefabric, are entirelyavoided by using the improved dipping-frame of my invention.

It consists of two horizontal bars, a a, fixed parallel to each otherupon one or more crossbars, b b, by socketso and set-screws d, as shown.

The bars a to are each provided with a row of teeth, a, each having aslit, f, at the end, in which the fabric 9 is inserted and secured by apin, h, passed in an inclined direction through holes in the end of eachtooth e, as shown, there being a number of these holes to permit theready insertion of the pin. The disposition of these teeth and pins forsecurely and easily suspending and removing the fabric is one of thefeatures of my invention.

The fabric being hung in a vertical direction, and so as to be entirelyfree during the immersion, all liability of crumpling and injury theretois thus avoided.

In order to suspendthe fabric, one of its corners is inserted in a toothof the frame, and it is then taken across to two teeth of the oppositeframe, in which it is secured without being pinched. .It is thenreturned to two other teeth of the first frame, where it is secured inlike manner, and so on, as indicated by dotted lines in Fig. 1, untilthe whole of the piece is thus suspended vertically in the frame.

In order to equalize the vertical tension of the fabricf during itsimmersion into the dyevat, small weights of lead, glass, or othermaterial are attached by a wire passing through holes made in the saidweights to the bottom edge of each fold of the fabric. The fabric isthus suspended freely and maintained. always at the same tension whilein the vat by means of the weights. The shrinking of the fabric in onedirection during its immersion is compensated for by the action of theweights, while it may be regulated in the other direction by varying thedistance between the centeringbars, which may be shifted upon thecross-bars by simply loosening screws d.

The apparatus may be easily cleaned, and may be used for any colors.

By these means the dyeing is rendered more perfect.

The apparatus may be held in the hand or suspended by any known means,such as a travcling or other crane or tackle, both while at taching thefabric and for transferring, dipping, and agitating it in one or morevats, c.

After the several dyeing operations have been completed the fabric isheld by the folds and the pins quickly removed. If the pins becomeoxidized, they are replaced by new ones.

Shades of great regularity are in this manner obtained.

The dipping-frame, which is supported upon the vatj in the positionshown in Fig. 3, may also be employed for drying fabrics, whereby thenecessity of handlingis avoided and creasin g and other damage to thefabrics prevented.

I am aware that nets and the like have been held distended by means ofweights, and do not claim, broadly, the use of weights on suspendedfabrics.

I claim- 1. In a tenter or dipping frameforuse in dyeing, theconstruction of bars a, having teeth provided with a slit,f, at theirend, in cornbiedge of each fold of the fabric to be dyed, subnation witha pin, h, securing the fabric into stantially as specified.

the said slits, as and for the purpose set forth. ANDRE LYON.

2. In combination with the tenter or dipping Witnesses: 5 frame and itsvertical suspenson-teeth e and R0131. M. HOOPER,
